I am using the Promise 20276 controller on my 8INXP motherbaord to run my CDROM drives.
The problem is that I dont think windows is accessing the drives as DMA devices. When I use either of the writers the system goes laggy, ie jerky mouse movements, slow reponse to clicks and key presses and even MP3 playback is choppy.
Anyone know what I can do to remedy this? There are no control panel options for the Promise controler so I cant exaclty see whats going on.
Thats the short version of my sturggle with the Promise controller, if you need more info to maybe explain whats going on then please ask.

did you by any chance reset in BIOS to ATA instead of Raid? Since cd-roms are ATA-33 it is best to connect them on IDe1 or 2.
OP
I have got the BIOS set to ATA133 mode not RAID for the promise controller.
Since I posted that message I have moved the CDROMs to the normal IDE controler and attached a 120 gig HD to the Promise controler and it seems to work OK, But I'd kinda like to share out the drives and put two CDROMs on the Promise controler.
